PH value exceeds the standard 5. Unqualified fiber content Fiber content is the main quality index of textile products. The quality of raw materials of textile products is one of the important factors that determine the value of products.

These dyes are used in the dyeing of underwear. When they come into direct contact with human skin, their toxic components will be absorbed and diffused by the skin. They will decompose under special conditions to produce more than 20 carcinogenic aromatic amines. After activation, they change the DNA structure of the human body, causing Lesions and inducing malignant tumor substances cause malignant diseases such as bladder cancer, ureter cancer, and renal pelvis cancer.
Even more terrible is the long latency period of cancer caused by aromatic amine dyes, which can reach 20 years.
These toxic dyes are far more powerful than formaldehyde because formaldehyde has an odor, is easily distinguishable, and is easily soluble in water. After consumers buy back clothing, they usually wash it with water to remove most of the formaldehyde; but the decomposable aromatic amines are not only insoluble in water, but also indistinguishable from the appearance of textiles.
If the bra is easy to fade after washing, sweating, rubbing, and light, it may contain decomposable aromatic amine dyes, which may be potentially carcinogenic.
pH is the pH, which refers to the pH of the fabric in clothing. Human skin is weakly acidic, which helps prevent the invasion of some bacteria. If the PH value of the underwear is not up to standard, the natural barrier of the skin will be damaged. After being exposed to strong acid or alkali, it will be forced to reduce skin immunity and cause irritating skin damage.
Wearing underwear with unacceptable PH value for a long time will cause itching of the skin, which will lead to severe skin inflammation and skin pimples and erosion.
